Sure ill have some shots,
No never, i already raced and trained a ton of miles in hills, bad surface, cobble stones, etc and its totally secure, of course its not the same as a bolted box. Im pretty sure dual sidded tape will damage the paint if youre not very careful when removing it.
Oh also i cutted the dual sided tape in half and glued a bit apart from the center of the box to try to make that gap between round and flat even smaller and provide a bit more leverage in the side to side movement (not sure you can understand what i mean).
